I am still unsure if this device measures long term actual kwh values? Could I enter $1 per kwh as a workaround since it measures cost?

Yes, it does measure long term. After 30 mins of being plugged in it switches to an "averaging mode" where it will track average cost based on your personal usage either on a monthly or yearly interval (by means of both cost and energy use). Also, you can fully cusomize the cost per kWh to provide an accurate cost estimation based on your home energy rates.

I have noticed no difference in electricity cost when using. It has been a satisfying investment for me.

Hi Mr. Hogan,I installed a Kill-A-Watt from Radio Shack tonight. While using an internal Seagate 500GB hard drive the meter shows usage is 5 Watts and .07 amp draw. The figures are different from one electric provider to the next. As an example, my local electric company charges me 12 cents per kWh during peak season and 11 cents during off peak season. It's costing me $5.26 per/year running 24/7/365.It's been running flawlessly since December 25, 2012. Yes, over a year and I share family pictures to lots of family members. Very easy to use.I hope this helps.Thanks,Terry Mundy Hi Mr. Hogan,I installed a Kill-A-Watt from Radio Shack tonight.

Yes. You can manually input your cost per kWh and it will incorporate it into its calculations.

I just started testing using a "kill a watt" meter($20) in cleveland. Skies that look like an ad for prozac. 65 watt max so far with 1killowatt hour accumulated over 1 week. My garage roof angle isn't the best(west). More data soon, follow up. Kw is a load measurement, kwhour is accumulated consumption.

At the bottom of the unit, it states: 18W. This is for the 2-speed unit. So if you pay 9.5 cents for a kilowatt of electricity then 9.5c * 0.018kW = 0.17 cents for an hour of use. For a full 24 hour you'd pay 24 * 0.17c = 4.1 cents. And so for a continuos 24 hour operation 365 days a year, your bill would be 4.1c * 365 = 1,497.96 cents which is $14.98. I'd say that's not bad.

Perfectly, that is what this product does. Just install on the sub-panel and it will give kWh being used from that panel.

Yes it accumulates and tells you for how long it's saved the data. It tells you the cost as well as long as you setup the the kw/h price in the settings.

That's a very tough math problem, James! Since you're using 0.015 kWh per day, that's 1 kWh every 67 days. Depending on your power company, 1 kWh probably costs you about 15 cents, so you'd be saving about $1.00 per year...not too impressive. The main reason I bought this was not to save money, but to make it possible to install a security light without needing an outlet.

Yes - As you repeatedly press the Meter button, the display cycles between (first for the connected device) Watts, Volts, Amps, Kwh, Elapsed Time, (then "Saved" quantities) Watts, Amps, Kwh, Elapsed Time. I'm not sure how the "Saved" quantities are calculated, so I ignore them.

The Lascar works great for what it is made for but not the best device for your purpose. I would think something like the following would work better. You would have to install it though in some way that they didn't have access to it. http://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU/ref=sr_1_1?ie=UTF8&qid=1403682570&sr=8-1&keywords=watt+meter

The device will record power usage for any period of time you require it to. So you can record for 1 hour, 1 day, 1 week or 1 month. For an appliance that runs intermittently (like a dehumidifier) you may wish to record usage for 1 week. Then you can extrapolate for the month by multiplying the 1 week consumption by 4. I will not record each interval the device runs separately however. So if you're looking for a series of readings representing each time it ran during that 1 week period, it will not do that. Hope this helps answer your question!

Not sure, I use this at a room I rent when I travel for work and the electricity is included in my bill. Although they haven't said that it went up any. I have used it for two summers.

Pretty sure it will not work for net metering. you might try the ted 1001. This will go both positive and negative for energy readings.

The Efergy displays Watts. Both instant current Watt readings, daily totals and daily averages. Local rates can be entered to show costs, but that feature is not necessary to use.

Don't know yet. Delivered as a gift out of state. Did you try their web site? There's also a number of sites that rate these devices, so they might include energy info.

Please see my answer under the topic "Is it energy efficient?" for an estimate of the maximum monthly heating bill from this unit and how to calculate the cost based on your electric rates and anticipated use.
